Mega Man Battle Network 4 - Red Sun (Europe)

Released in Europe in 2004 by Capcom, Mega Man Battle Network 4 - Red Sun (Europe) is one half of the fourth core entry in the beloved Mega Man Battle Network franchise for the Game Boy Advance. Set in the futuristic Net Age, where every person carries a Personal Terminal (PET) device housing a sentient digital companion called a NetNavi, the game follows 11-year-old Lan Hikari and his partner NetNavi MegaMan.EXE as they navigate both real-world and digital threats.

As they progress through tournament rounds, they uncover a shadowy conspiracy tied to a rogue asteroid on a collision course with Earth, forcing the pair to team up with unlikely allies to stop a global catastrophe. As the Red Sun exclusive version, this European release features unique version-locked content not found in its Blue Moon counte

Game Guide

Mega Man Battle Network 4 - Red Sun’s unique tactical battle system rewards preparation and strategic folder building, so follow these tips to get the most out of your playthrough, including unlocks for exclusive Red Sun and European version content. First, for early-game progression: prioritize collecting core attack chips like Wide Sword, Hi-Cannon, and Fire Stage chips in your first 10 hours of play, as these will let you quickly clear random virus battles and early tournament opponents without wasting higher-value chips. As a Red Sun exclusive feature, you can unlock the powerful Sol Cross MegaMan form by completing TorchMan’s optional side quest after you beat the first Eagle Tournament preliminary round. Sol Cross grants permanent immunity to fire panel damage, boosts all fire elemental chip damage by 50%, and lets you charge your standard buster to fire explosive fire shots, making it unbeatable against water-type Navis like BubbleMan and Aquaman. For tournament progression: between every tournament match, explore every corner of both the real world and the internet area, as hidden secret opponents are scattered across each zone that drop rare, version-exclusive chips you cannot get anywhere else. For the European release specifically, do not miss the exclusive Euro Medal side quest: after beating the first tournament, talk to the backpack-wearing tourist near the ACDC Town train station, and complete his request to delete 10 fire viruses in the Undernet to get the limited-edition Euro Medal chip, which deals 400 damage to all enemies on the grid and is not available in any other regional release. When building your battle folder, stick to exactly 30 chips with no more than 5 copies of the same chip, and always include at least 3 recovery chips (Recover 200 or higher), 2 panel grab chips, and 1 barrier chip to handle unexpected boss battle mechanics. For the late-game asteroid arc, stock up on fire elemental chips like the Red Sun exclusive Volcano 3 and Fire
